Is it possible that Nikola Tesla’s 3 6 9 theory of the universe holds water? His obsession began with his fixation on the number three. It might have something to do with OCD that kept him going around the block three times before entering the hotel, but he was certain that those three numbers hold the key to the Universe. To understand his fixation with those numbers, we have to think as Nikola Tesla taught. It has to do with complicated mathematics and human history. Scientist Marko Rodin believes that 3 6 9, then, represents a “flux field” or a vector from the third to the fourth dimension. Maybe Tesla’s 369 theory really reveals something, but it seems that it is lacking a mastermind behind it.
